[A case of selenium poisoning in weaned piglets; the persistent one wins]

A case of selenium poisoning involving eighty approximately nine-week-old piglets is reported. Feed and water were supplied with a dry feed hopper with nipple in the through. Clinical symptoms appeared within ten days after the feed-intake. The symptoms consisted in loss of condition (emaciation), drawn-in thin bellies, long hair, loss of appetite, hard, dark faeces, cerebral symptoms and mortality. Autopsy was performed on a total number of four piglets, in which severe hepatic degeneration was detected. When pig prestarter (creep feed) was substituted for piglet-raising feed (weaner-diet), the condition was gradually restored to normal within a few days.
